Let's first stipulate that I2 and I1c refer to the same haplogroup --- M223
positive. FTDNA believes the old I1c must be given the I2 status for good
reasons. But the M223 positive remains the same. You should only know the
difference between a I1c versus I2 status if you tested P38 SNP.

I believe your 20 through 24 are Northern variety of I2 a.k.a. I1c. I don't
recognize haplotype 19 at all and will have to look at it more deeply.
